Kreisstraße
A Kreisstraße (literally: "district road" or "county road") is a class of road in Germany. It carries traffic between the towns and villages within a Kreis or district or between two neighbouring districts. In importance, the Kreisstraße ranks below a Landesstraße (or, in Bavaria and Saxony, a Staatstraße, i.e. a state road), but above a Gemeindestraße or "local road". Kreisstraßen are usually the responsibility of the respective rural district ( Landkreis) or urban district ( Kreisfreie Stadt), with the exception of high streets through larger towns and villages. Kreisstraßen are usually dual-lane roads but, in a few cases, can be built as limited-access dual carriageways in densely populated areas.
